SOLE-LAYING MACHINE.-

SPECIFICATION lforming part of Letters Patent No. 362,447, dated May 3, 1887.

Application filed February 8, 1887. Serial No. 926,917. (No model.)

.To all whom it may concer-n.-

Be it known that l, CHARLES E. HOLLAND, of Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Sole-Laying Machines, of which the-following is a specification.

This invention relates to machines for pressing soles against lasted uppers of boots and shoes, while the cement which temporarily secures said soles and uppers together is setting or hardening. In Inachines of this class the last on which the upper is placed is supported by a jack, and the sole is placed on an elastic bed, which is forced toward the bottom of the last, and by its elasticity molds or con` forms the sole to the shape of thebottom of the last.

My invention has for its object to provide- 2o certain improvements relating to the sole supporting audvmolding bed, the means for raising and depressing the saine and holding it raised and depressed, and to the jack and its supporting and operating' devices; andgto these ends my invention consists in the several improvements which l will now proceed to describe and claim.

Oftheaccompanyingdrawings,formingapart of this specification, Figurel represents afront elevation of a sole-molding machine embodying my invention. Fig.42 represents' a rear elevation of the jack-supporting cross-head. Fig. 8 represents a section on line ac as, Fig. l. Fig. 4 represents an enlarged section Online y y, Fig. 2. Fig. 5 represents a side elevation ofthe machine. Fig. 6 represents a section on line e e', Fig. 5. Fig. 7 represents a `section on line y' y", Figs. 1 and 8. Fig. 8 represents a section onilinex x', Fig. 5. Fig. 9 represents a detail view.

The same letters of reference indicate the same parts in all the figures.

In the drawings, a represents the supporting frame or base, to whichare rigidly attachedvertical guiderods b b, on which thelastsupporting jack and the holder or carrier for the sole pressing and molding pad or bed are adapted to slide. The jack is composed of two end pieces, 2 v2, having sockets adapted to 5o slide on t-he rods b b, a central piece, 3, having trunnions 4 4, journaled in sockets 5 5 onthc end pieces, 2 2, and also having a guide or rib, c, extending from front to back of the machine, and tWo standards. d d', the former having a spindle to enter the socket in the rear end of the last, and the latter a rest, c, pivotally connected to its lower portion to support the shoe while the same is being operated upon.

The molding` pad or bed is composed of astrip of rubber or other liexible material supported 6o by aiholder or frame, f, preferably of cast-iron, having trun'nionsg g journaled in sockets in the sliding carrier h. Arms or levers i) i are pivoted to the holder f, and to their swinging ends are attached the ends of the pad 7a. Said 65 levers have sockets at their top for the reception of springsjj. lu the center of the frame is a sliding support for the shank-pressing portion 0f the pad. Said support consists of a base, Z, adapted to be moved in a dovctail 70 groove, m, to secure proper adjustment as to position. The base Z is provided with a socket adapted to receive a spring, o, supporting a block or pad, 0, Figs. 3 and 5, conforming to the curvature of the shank of the lasted shoe, so that when the pressure is applied to mold the sole to the shoe said pad can readily be adjusted to different sizes of shoes.

The block or pad o is made of metal, and has a smooth surface in contact with the pad It', so SO that it can slip freely on the latter. Said block is jointed to its shank o2, so that it can tip freely toward the front or back of the pad k, and said shank is supported only bythe spring o3, so that the block has a considerable freedom 85 of movement in all directions, whereby it is enabled to conform to different shapesy and sizes of shank-bottoms.

-The yielding molding-pad k may be composed of rubber, felt, or any other suitable 9o ayielding material, and is normally kept'taut by springs j j, interposed between the ends of the frame and the levers 'i It will be seen that when pressure is applied by the pad to the sole the levers z' t' will yield or be drawn 95 inwardly sufliciently to allow the elastic top to conform to the shape of the bottom of the last and will mold the sole thereto, while the resistance of the springs j j, developed by this movement, will exert sufficient tension on the Ico elastic pad to mold the sole to the form of the bottom of the last. At the same time the shank-pressing block gives the pad the requisite pressure against the shank portion of the sole.

rlliemeans for reciprocating the sliding frame constitute an important feature of my invention, and the construction and arrangement of the several parts having this object in view will next be described.

1) represents a drivingpulley loosely journaled on a shaft, q, Figs. l and (i, and adapted to be rotated by any suitable means. Said pnlley is secured on said shaft by a split collar, r, on the outer end of the shaft. A clutch, s, on shaft q is rotated therewith by means of a feather and groove, l, Fig. G, and is adapted to be thrown into or out of connection with a like clutch, s2, on the driving-pulley p. Said clutches,when thrown into gear,serve to rotate the main shaft q, which operates the sole pressing devices and the jack, as hereinafter described.

A gearwheel, a, on main shaft q meshes with a larger gear-wheel, c, on the second shaft, q". The gear-wheel c is provided with an eccentric, yuf, Fig. 6. Said eccentric is snrrounded by an eccentric-strap, a, which strap is connected at b', Figs. 7 and 8, to an arm, c', which arm is connected at d to a lever, c', journaled in bearings at its lower end on the base a of the machine. A lever,f, is connected at (1' to lever e', and extends upwardly, and is pivoted to ears It h on the lower edge of the sliding frame h, supporting the padholder.

It will be seen that the levers e'f form the members of a toggle-joint, and the rotation of the eccentric w reciproeates the arm c', and through it the levers e'f are caused to move the sliding frame the required distance. The construction just described is best shown in Figs. 5, 6, and S.

The rotation of the drivingshaft causes the eccentric lw to alternately raise and lower the frame 7z,and the pad-holder and pad supported thereby, by alternately moving the levers c' f into and out of alignment, said frame and pad-holder being depressed when said levers are thrown out of line with each other, as shown in Fig. 5, and raised by the movement of said levers into line with each other.

By reference to Fig. 5 it will be observed that when the sliding frame h is depressed, or in the position to begin its upward movement, the position of the eccentric 1r (shown in dotted lines) is such thatits rotation will not move the levers cf' until it has passed the center of rotation, and while passing said center the mechanism remains stationary, thus giving the operator time to unjack7 the shoe and place another thereon. The same conditions exist when the eccentric is on the opposite center andthe sliding frame is raised to its highest point, the mechanism remaining stationary while the cement on the sole is setting.7

The pulley p and gear c are loosely fitted to the shafts q q2, while the gear-wheel u is fastened to the main shaft by apin, i, and thc clutch 8 is constructed to rotate with the shaft and slide thereon into and out of engagement with pulley p, the pulley rp and gear u being caused to rotate with the shafts by the engagement of the clutch s with the pulleyp,a11d made loose by the separation of said clutch and pnlley.

In machines of this class it is usual te give thejack a limited vertical movement on the guide-rods b I), said jack being depressed and locked in its lowest position before the solepressing pad is raised, and released and raised after the pressing operation, a wider opening between thejack and pad being afforded than there would heif the jack were not thus movable. Heretot'ore ithas been the practice to secure the jack in its depressed position by means of spring-pressed pawls engaging with ratchet teeth on the front sides of the standards b b. This construction renders it necessary for the operator to release the jack (when pressure has been applied) by hand. This construction not only requires time needed for other purposes, but makes the construction more expensive, as the ratclictteeth require to be hardened to obviate rapid wear from frictional Contact of the pawls with them, it being necessary to forni the ratchet teeth on pieces separate from the upright standards and tit said pieces into the uprights after the teeth are hardened. To obviate this objection, .l construct split collarsjj, provided with ears It 7c', Figs. 2 and Said collars are adapted to closely lit the upright standards b b, and a screw-threaded rod, Z', is passed through the ears 7a 7a', and nuts m' m screwed tightly on said rod to engage the ears closely and form shoulders therefor, the section of each ear adjoining said nuts having thehole large enough to slip onto the rod, and the other section of each ear being screw-threaded, so that when rod l is rotated in one direction the movement will cause said collars to grip the standards tightly, and when rotated in the opposite direction the collars will bc loosened suiliciently to slide freely up and down on the standards b I).

An arm or lever, n', is attached to one end of rod Z, and to said arm is attached a rod, o, Figs. l and 5, extending downwardly, and connecting with a horizontal arm, p', pivoted at its center to the frame of the machine, and engaging with another rod, g, adjustably connected at its lower end with adisk, r', attached to the main driving-shaft q. Said disk is provided with a slot, s', by which means the th row of its wrist-pin t can be regulated and the mechanism properly adjusted.

By the meansjust described thejack is automatically secured when drawn down to receive the pressure of the molding-pad k, the movement of drawing down said eross-hcad by means of treadle u and rods o o causing the arm a to be elevated, the connections thereof rei'naining stationary, the movement IIO f of elevating said arm a rotates rod Z and closes sary to tighten the collars on the standards?) bv sufficiently to hold the jack in the position required until t-he disk r has rotated past its center, which rotation causes the arm a to rotate in the opposite direction, thereby unscrewing rod Z and loosening ears k k', allowing springs w' to raise the jack from the pad.

The ears L" k are so arranged in relation to the jack and cross-head that when the latter is drawn downwardly said ears follow down through the instrumentality of the head a2, which bears on the center portion of the rod and forces it down therewith.

' The abovedescribed mechanism is so timed with relation to the sole-molding mechanism that when the pressure on the sole has been completed thecollars are loosened, and not before. The means just described for holding down the jack and then releasing the same are a great advantage and saving both in the operation and construction of the machine and `constit-ute an important feature of'my invention. 4

I have found that in the operation of machines of this, class better results could be obtained if the jack'could be adjnstably connected toV the cross-head-that is, if it were adapted to oscillate to a slight extent, so that the last thereon can swing in the direction of its length, the boot or shoe would :more readily adapt. itself to different conditions when receiving the pressure of the moldingpad. In molding soles to different styles of lasts it is an advantage to have the jack conform to a limited extent to the pressure. To these ends I have shown the jack provided with a central piece, 3, having trunnions et et journaled in sockets 5 5 on the end pieces, 2 2, and having springs 6 6, adapted to hold said central piece in a central position when pressure is not exerted upon the jack, but allowing it to oscillate against the pressure of said springs when necessary, the oscillatory movement which is thus afforded being in the direction of the length of the boot or-shoe.

In case it is desirable to stop the rotation of the drivingshaft automatically when the sole-pressing pad is at each extreme of its movement, the means next described may be employed for automatically throwing the clutch s out of engagement with the clutch sl on the driving-pulley p once during each ro tation of the driving-shaft and during the above-described periods of rest of the solepressing pad, so that said periods can be continuedindefinitely,and will be terminated only at the will ofthe operator; or, if preferred, the clutch s may be thrown out of engagement when the jack is at one extreme only of its movement-1T. c., when the sole is beingpressed against the last and while the cement'is hardening.

b2 represents a "shipper,7 pivoted to aflug, c2, on the frame of the machine. Said shipper is provided with arms partially encircling thel clutch s. Said arms are provided with pins e2, engaging with a groove, d, formed in said clutch. rIlhe lower portion of the shipper is provided with a like pin,f2, (shownin dotted lines in Fig. 1,) adapted to engage with an angular or cam-shaped lug, g2, on a collar, h2, on shaft q2. Said collar has a spring, ji, one end ot' which is secured td a collar, 2, rigidly affixed to shaft q, and theother end to the collar if. The collar l# is loosely fitted to the shaft, and is provided with aslot, 12, (see Fig. 9,) in which is located a pin, j", rigidly inserted in the frame (t, which pin holds said collar in the position shown in Fig. 1. The machine being started bythe throwing into gear of t-he clutch s with pulley p, the collar lt2 moves round by the tension exerted thereon by collar t: against springjg, the lug g2 causes the lower end of shipper b to be forced outwardly until said clutch has been disengaged from engagement with pulley p, and at the same moment pinf2 passes over lng g, when the force of spring ji throws collar h'l back to the position shown in Figs. l and 9. Clutch sis adapted to be engaged with clutch s'Z by means not' a lever, a3, pivoted to an ear, a, on the frame a. Said lever is pivoted at its lower end to one of the arms of the` shipper cZ on the rear side of clutch s, and at its upper end to a rod, a", suitably secured in bearings on the frame a, and provided with a knob, af, on its outerend, and is adapted to lbe moved longitudinally in its bearings by the operator to throw clutch s into gear with clutch s'l on pnlley p.
